Brandon Wu 91dd844aa4 Recommit [RISCV] RISCV vector calling convention (2/2) (#79096) (#87736) ...

Bug fix: Handle RVV return type in calling convention correctly.
Return values are handled in a same way as function arguments.
One thing to mention is that if a type can be broken down into
homogeneous
vector types, e.g. {<vscale x 4 x i32>, {<vscale x 4 x i32>, <vscale x 4
x i32>}},
it is considered as a vector tuple type and need to be handled by tuple
type rule.
